altEN Biogas

altM is an alternate materials company. We harness readily available yet often overlooked biomass sources, specifically post-harvest agricultural residue, as our primary input material.altEN Biogas is a feedstock enhancement solution designed to improve biogas production from lignocellulosic biomass by addressing the limitations of high lignin content and other unconvertible components. By increasing the accessible carbohydrate fraction in the feedstock, it enables more efficient microbial conversion and improves adaptability across a wide range of biomass inputs.

‍

The result is a more consistent and reliable feedstock supply, supporting stable biogas generation with reduced formation of undesirable by-products such as H₂S. Designed for integration with existing systems, altEN Biogas streamlines plant operations, improves overall efficiency, and enables more dependable bioenergy production.
